Book excerpt: Excerpt from Revision of the New World Species of the Tribe Donaciini of the Coleopterous Family Chrysomelidae The North American species of Donacia are very variable and um fortunately in most of the characters useful in distinguishing species and the study of them was at times laborious as a great 'number of specimens of most of the species had to be examined and studied to ascertain how far the variations go and also to become thoroughly acquainted with the difierent species. In addition carefully reading the numerous original descriptions of American Donacias described by French, English, German and American authors has taken a good deal of time. However, the result has been gratifying as a number of mistakes in the identification of some of the species were found and could be corrected.
